A statistical model to determine the capacity of battery–supercapacitor hybrid energy storage system in autonomous microgrid.

Highlights: [•] A new hysteretic loop control strategy for frequency regulation is developed. [•] A statistical model to determine the capacity of BSHS is proposed. [•] Monte Carlo simulation is implemented to the statistical model. [•] The capacities of BSHS at different cumulative probability levels are determined. [•] The control strategies have close relationship with the capacity of BSHS. [ABSTRACT FROM AUTHOR]
